WISeSat and Swiss Space Command of the Swiss Armed Forces Complete Pilot Phase and Prepare Next-Generation WISeSat 6U Mission Planned for November 2026
WISeSat and Swiss Space Command of the Swiss Armed Forces Complete Pilot Phase and Prepare Next-Generation WISeSat 6U Mission Planned for November 2026
Pilot phase validates key technical and operational foundations for a sovereign, secure Swiss space communication architecture.
Next-generation 6U platform intends to form the first building blocks, fully funded, of WISeSat's Quantum Space Orbital Cloud (QSOC) roadmap.
Geneva and Bern, Switzerland – April 13, 2026 - WISeKey International Holding Ltd ("WISeKey") ((SIX: WIHN, NASDAQ:WKEY), a leading global cybersecurity, blockchain, and IoT company, through its space technology subsidiary WISeSat.Space ("WISeSat"), and semiconductors, PKI, and post-quantum technology subsidiary SEALSQ Corp ("SEALSQ") (NASDAQ:LAES), today announced the completion of a pilot phase in their strategic partnership with the Space Command of the Swiss Armed Forces.
The collaboration, initiated in 2022 and further strengthened in 2024, has focused on evaluating technical and operational building blocks relevant to a future Swiss sovereign and quantum-resilient space communications infrastructure.

During this pilot phase, WISeSat, SEALSQ and their partners conducted satellite missions, payload integration work and secure communications testing designed to assess architecture options, operational concepts and future government and defense use cases. The program has provided technical validation and practical lessons for the next stage of development.
WIseSat 6U – The Next Phase towards QSOC
Building on these results, WISeSat and the Swiss Space Command continue their partnership. WISeSat is now preparing a next-generation 6U mission, planned to launch in Q4 2026. The new platform is intended to offer greater payload flexibility, longer mission endurance and broader application potential for secure communications and other sovereign space infrastructure uses.
The first 15 next-generation 6U satellites planned by 2027 are intended to form the initial elements of WISeSat's Quantum Space Orbital Cloud ("QSOC"). WISeSat is expected to own and operate these satellites and the associated space and ground segment in cooperation with the Swiss Space Command as part of its program architecture, while SEALSQ is expected to contribute its quantum and cybersecurity technology stack across selected constellation resources and capabilities.
A Platform for the Swiss New Space Ecosystem
The new 6U generation is also intended to serve as a modular in-orbit platform that will allow Swiss space companies to test and validate selected products, subsystems and applications in a real mission environment, and therefore contribute to the Swiss innovation ecosystem.
WISeSat's objective is to provide a practical framework through which emerging Swiss New Space players may gain access to flight heritage, accelerate development cycles and demonstrate technologies relevant to sovereign and secure space infrastructure.
QSOC Roadmap to 2033
The 6U mission and the first 15 satellites planned by 2027 are intended to constitute the first building blocks of WISeSat's QSOC roadmap, with full operational capability currently envisioned for 2033.
As the programme develops, future platform generations could support a broader set of payloads and services, depending on technical validation, mission priorities, financing and customer demand. These may include secure communications payloads, advanced post-quantum cryptographic functions, sovereign identity and trust infrastructure, direct-to-device connectivity, optical communications, selected sensing capabilities, onboard processing, secure data storage and other digital infrastructure services.
This roadmap reflects WISeSat's ambition to help establish a Swiss-led, secure and scalable orbital infrastructure serving both sovereign and commercial applications.
Col GS Ludovic Monnerat, Commander, Space Command, Swiss Armed Forces / Air Force, noted, "The completion of this pilot phase has helped clarify technical possibilities and operational considerations for the next stage of development, including, for our command, regarding highly secure space-based communications. The planned 6U mission represents an important next step in assessing how sovereign and secure space capabilities could evolve for Switzerland, while giving unique opportunities for our ecosystem to test and mature new technologies."
Carlos Moreira, Founder and CEO, WISeKey, added, "Completing the pilot phase with these satellites in orbit is a milestone that few partnerships at this level of technical complexity achieve in two years. It reflects the depth of trust, shared vision, and engineering excellence of both teams. With the WISeSat 6U launch on the horizon, we are entering a new chapter in Switzerland's quantum-secure space program."
